Abstract: The instant disclosure relates to a lubricant composition having an oil of lubricating viscosity, a polymeric surfactant compound that is an acylated polymer having a number average molecular weight of about 500 to about 50,000 where the polymer comprises a branched olefin having from 8 to 30 carbon atoms. The acylated polymer can further be reacted with an amine or alcohol to form an amide, imide, ester or combinations thereof. The present disclosure further relates to lubricant compositions that exhibit good dispersancy and viscometric performance.

Abstract: The instant disclosure relates to hydrocarbyl- (e.g., alkyl-) benzene sulfonate detergents and their salts, where the hydrocarbyl group includes moieties equivalent to 5 to 10 carbon branched polyene compounds. Such compounds and their salts are useful as lubricant additives. The detergents disclosed herein may solve at least one problem of providing anti-wear performance, frictional performance, oxidation performance, viscosity performance, and detergency.

Abstract: A phosphorous- and sulfur-containing additive and its use to impart anti-wear properties to oleaginous compositions such as fuels and lubricating oils, particularly power transmission compositions, such as automatic transmission fluids, is disclosed. The additive comprises a mixture of products formed, for example, by simultaneously reacting (1) a beta-hydroxy thioether, such as thiobisethanol, (2) a phosphorous-containing reactant, such as triethyl phosphite and (3) optionally, a nucleophilic reactant capable of reacting with the episulfonium cation ##STR1## to form thioether species.

Abstract: A phosphorous- and sulfur-containing additive and its use to impart anti-wear and/or antioxidant properties to oleaginous compositions such as fuels and lubricating oils, particularly power transmission compositions, such as automatic transmission fluids, is disclosed. The additive comprises a mixture of products formed by simultaneously reacting (1) a beta-hydroxy thioether, such as thiobisethanol, and (2) a phosphorous-containing reactant, such as tributyl phosphite. The reaction is carried out under reduced pressure conditions (e.g., -40 KPa to -100 KPa) to limit the amount of thioether species in said additive to less than about 45 mole %.
